.510 cal airgun "4x4" .50 caliber air rifle bigbore pcp power

Amazing! What's next? 110 cal? I think you could probably kill most anything on the North American continent with this one (maybe big bears excepted). Any pressure remaining for a follow up shot or 2?

KingLoopie1, Glad you enjoyed the video! Yes, definitely have enough pressure left for a few more high power shots, even when I'm using the .510 cal barrel. I haven't tried a shot string with the .510, but with the .458 barrel, I got 7 shots of 500fpe each. So that makes about 3,500 useable FPE from one fill of the 380cc tank. A little scary when its throwing 405 and 575 grain bullets.

@1227air500 These are excellent results for both power level and air efficiency, I have only got better efficiency at lower power (e.g 3090 fpe total from 185cc) with 28" barrel. Your electronic system must eliminate valve bounce and have rapid actuation.

@Rakemaan . Thanks for the comments. I looked at some of your videos and you work with quite a variety of equipment. Estimating the start and stop pressures on your 185 cc gun, that really is an efficient shooter. Efficiency is such an elusive target. This gun doesn't have a hammer, it uses an air operated valve that I built. Getting it to close repeatably was the trick.

The video is too long in the middle. After the shooting part, skip to the end.
